I do not collect stamps, but the hobby has tempted me. I am always fascinated by the art on stamps, and I love to shop for them. This year, I fell in love with the "150 Of Photography" collection, and quite frankly, am having a hard time using them.I've not heard of Machine stamps before today, and was interested enough to do a bit of reading on their history. They are quite the big deal as it turns out.Nice to visit here this morning, Andrea
